Question

Which data structure in a compiler is used for managing information about variables and their attributes?

• A. Abstract syntax tree
• B. Symbol table
• C. Semantic stack
• D. Parse table

Answer 1

The data structure in a compiler used for managing information about variables and their attributes is the Symbol Table.

The Symbol Table is a crucial data structure in compilers that keeps track of identifiers (such as variables, functions, etc.) and their associated information, including their types, memory locations, scope, and other attributes. It plays a vital role in semantic analysis, type checking, and code generation phases of the compiler.
